AI Technical Summary

Technical Problem

Traditional swing-out side doors occupy a lot of space in textile printing and dyeing workshops, resulting in low space utilization. They cannot meet the production needs of high efficiency, energy saving, and space conservation, and are inconvenient to operate, making it difficult to meet the requirements of intensive and automated production.

Method used

The vertical lifting door adopts a cylinder chain, which uses a double-headed cylinder to drive the chain and sprocket to achieve vertical lifting of the door. Combined with a dust removal component and a safety locking mechanism, it ensures the stable operation and safety of the door.

Benefits of technology

It solves the problem of wasted space, improves space utilization and production convenience, extends equipment life, reduces safety risks, adapts to high-temperature operating conditions, and achieves flexible control and efficient opening and closing.

Abstract

The invention belongs to the technical field of overhead doors, and particularly relates to an air cylinder chain vertical overhead door which comprises a door frame, two mounting racks are arranged above the door frame, double-end air cylinders are connected to the front side walls of the two mounting racks, and two overhead doors are arranged in the door frame in a sliding mode. The moving ends of the double-end air cylinders are connected with chains through connecting assemblies. The air cylinder drives the chain and the chain wheel to achieve the opening and closing mode of vertical lifting of the door body, a traditional side-hung structure is replaced, transverse door opening space does not need to be reserved, the problem of workshop area waste is thoroughly solved, and workshop rent and building cost are remarkably reduced; the left door and the right door can be independently controlled, use is flexible, the lifting height can be adjusted according to needs, and adaptability is high; the whole structure is simple and reliable, maintenance is convenient, an original box body and an original heating system of the device are not changed, the device can be perfectly matched with the high-temperature operation working condition of a textile printing and dyeing drying and setting machine, and the space utilization rate and production operation convenience are greatly improved.
